[TxMt] Horizontal scrolling in project drawer?

My project drawer used to scroll horizontally when I had several levels of folders open, now it trims letters from the middle of filenames. Why did this change and how can I change it back?

I don¹t recall changing anything in TM options and indeed I can¹t find this as an option anywhere. I did get some Apple updates recently; from the archives it appears that string squishing is a behavior of the system tree control so it is possible that something changed underneath.

Thanks for any ideas! Seth Cousins

(p.s. Fairly new to TM, I¹ve been using it for ~2 months and it¹s the best GUI editor I¹ve ever used.)
